lighting MH HPS or Cool whites

so i waz wondering what type of lighting is better is it like pot where you need MH for veg and HPS for flower, and these types are better for plant growth then conventional fluorescent tubes (cool whites). or is it they need the light to help induce pinning. but if i had a MH or HPS would this be more effective for these purposes the cool whites

Coolwhites are best for several reasons most noteable is amount of UV's produced as well as radiant heat issues.

well im a old weed farmer and if i know anything uvs given off buy cool whites is no where nere the high pressure sodium or metal highlide uvs or lumens but for the heat i can see that they would be good for a closet set or something but i have a room for this hobbie it would take me like 24 cool whites to add up to 1 600 watt hps but if that the best for mushrooms ok but i guess you need uvs for pinning and kill some types of uv sensative bacteria . but if i use cool whites is VHO(very high output)be better
any other opinons

By "amount of UV's produced" he meant that fluorescents don't produce UV whereas HPS and MH do. If you used HPS or MH without glass or some sort of UV shield you would kill your mycelium in very short order.
VHO doesn't matter. Since standard lights are cheaper they are a better choice. In fact, the light source doesn't really matter at all. As long as you have enough light to read by it's plenty. Brighter or dimmer doesn't matter.(within reason) 6, 8, 12, or 24 hours a day doesn't matter. There is no way to screw up the lighting, so don't worry about it.

I use natural lighting... My tubs are in my kitchen near the windows, and get sunlight...
HPS or MH would probably dry your shit up.

Casings are dark in color this makes radiant heating of the casing an issue it will warm and can easily create excessive transpiration (evaporation). Just something for you to watch out for and take into consideration.
